I'm not sure if it's just me, but the subtitles timing is off by quite a bit. Please reply if you are having the same problem. It could simply be my video, but I can't find any other links that seem to match with the subtitle .srt file. Please reply! Thank you for taking the time to sub this drama!
Which video file are you using and when did you download the subs? If it was right when it came out, the timing would be off since it wasn't synced yet and said so on the download page. Re download the subs and see if it works. Make sure to select "Auto-clean up of empty lines" especially if you are using VLC player.
